The NiteCore D4 is a universal automatic smart-charger that is compatible with most rechargeable batteries including IMR/Li-ion, Ni-MH and Ni-Cd batteries. The D4 has four battery slots, eliminating the need to own several chargers. It can recharge four batteries at the same time and each of the microcomputer-controlled charging ports can monitor and charge batteries independently.

The D4 detects each battery's status and auto selects the appropriate charge mode, either Constant Charge Current (CC), Constant Charge Voltage (CV) or Trickle Charge. An integrated LCD screen shows the current charging status of each battery, as well as voltage and current.

Constructed from ABS flame-retardant and resistant material, the D4 includes several safety features such as over-charge protection, auto-shut-off for fully charged batteries, and reverse polarity protection.

I was using an i2 before the D4, both great chargers. The D4 allows 4 batteries to be charged simultaneously with a digital display of the progress.

In terms of chargers, Nitecore lead the way. Reliable and safe, with manufactures guarantee.

Best one yet (18 June 2016)

Best charger on the market, I use rx200s and it was annoying Charing two batteries at a time when it requires 3. This charger has all the info you need on it and more, plus can charge four at a time which helps massively!

Great charger.......although (08 October 2015)

I bought this charger to replace my nitecore i2, as I have a growing number of batteries and mods. I recently got myself a 22650 mech mod. And bought this so I could charge them while my 18650's charged on the other. My problem arised when I tried to charge 2 22650 batteries, but they wouldn't fit. Even though this is a 4 battery charger, this is only 4 18650 and smaller. You can still charge 1 22650 at a time. The packaging needs to be more clearer from the manufacturer. Apart from that, this is a brilliant charger and a good upgrade, I like the screen and how it tells you everything about each individual battery. Service from the vapeclub was spot on as usual. Ordered it yesterday at 3pm, was at my door today at 9am. Brilliant as always hence why I am a regular customer and always use them for my vape needs.

Very good (05 February 2015)

The charger does exactly what it's meant to do, but in a very good way. The display makes it easy to estimate how long it will be till the batteries are fully charged, and the overcharge protection is a very useful feature. You can also turn the display off if the backlight anoys you.
